Abstract
Provided are lincosamide compounds for the treatment of infectious diseases. The lincosamides described herein are modified at the C-7 position of the aminooctose (northern) region, thus distinguishing them from lincomycin and clindamycin. Also provided are methods for preparing the lincosamide compounds, pharmaceutical compositions comprising the lincosamide compounds, and methods of treating infectious diseases using the disclosed lincosamide compounds.
